The MiiR® Kaleido 10-oz Wine Tumbler keeps wine, beer, and sparkling water cold. The trapezoidal design with a flare above the base makes it easy to hold, and since it's made of sturdy 18/8 stainless steel, when it's empty you can stow it in a cooler or pack for long days outside. The double-wall construction keeps cold drinks cold and the press-fit slide lid prevents splashes and spills (not leakproof). The MiiR® Kaleido 10-oz Wine Tumbler is fully backed by our Ironclad Guarantee and you can find it on Patagonia.com.
